Printed composite

Abstract

A printed composite including a substrate layer having an upper substrate surface for printing; an ink layer having an upper ink surface and an opposed lower ink surface, the lower ink surface being disposed on the upper substrate surface; and a protective layer covering the upper ink surface is disclosed. During use, the protective layer prevents the ink layer from being damaged, such as removal or discoloration, as could otherwise happen by exposure to sunscreen location. A method for preparing the printed composite is also provided.

What is claimed is: 
     
       1. A printed polyvinylchloride (PVC) composite comprising:
 a PVC layer having an upper PVC surface; 
 an ink layer having an upper ink surface and a lower ink surface, opposite the upper ink surface, the lower ink surface being disposed on the upper PVC surface; and 
 a protective layer comprising a solid component dissolved in a solvent component, the protective layer disposed on the upper ink surface of the ink layer, wherein the protective layer does not react with the ink layer and is configured to inhibit alteration of the ink layer from sunscreen for application on and protection of a user; 
 wherein the solid component comprises at least one of: 8%-13% (by weight of the protective layer) chloroacetate resin and 10%-20% (by weight of the protective layer) polyurethane. 
 
     
     
       2. The composite of  claim 1 , wherein the solvent component comprises at least one of: propylene glycol monomethyl ether propionate, ethyl 3-ethoxypropionate, and propylene glycol monomethyl ether acetate. 
     
     
       3. The composite of  claim 1 , wherein the solvent component comprises at least one of: 10%-30% (by weight) propylene glycol monomethyl ether propionate, 10%-30% (by weight) ethyl 3-ethoxypropionate, and 15%-30% (by weight) propylene glycol monomethyl ether acetate. 
     
     
       4. The composite of  claim 1 , wherein the protective layer comprises an air-drying transparent oil including the solvent component and the solid component, the solid component including a resin component. 
     
     
       5. The composite of  claim 4 , wherein the solvent component of the protective layer comprises at least one of: propylene glycol monomethyl ether propionate, ethyl 3-ethoxypropionate, and propylene glycol monomethyl ether acetate. 
     
     
       6. The composite of  claim 4 , wherein the solvent component of the protective layer comprises at least one of: 10%-30% (by weight) propylene glycol monomethyl ether propionate, 10%-30% (by weight) ethyl 3-ethoxypropionate, and 15%-30% (by weight) propylene glycol monomethyl ether acetate. 
     
     
       7. The composite of  claim 4 , wherein the air-drying transparent oil further comprises auxiliaries including a defoaming agent and a leveling agent. 
     
     
       8. The composite of  claim 1 , wherein the protective layer has a thickness of 0.005 mm to 0.02 mm. 
     
     
       9. A printed polyvinylchloride (PVC) composite comprising:
 a PVC layer having an upper PVC surface; 
 an ink layer having an upper ink surface and a lower ink surface, opposite the upper ink surface, the lower ink surface being disposed on the upper PVC surface; 
 a protective layer disposed on the upper ink surface of the ink layer, wherein the protective layer does not react with the ink layer and is configured to inhibit alteration of the ink layer from sunscreen for application on and protection of a user; 
 wherein the protective layer comprises an ultraviolet (UV) transparent oil including a polymer, a photosensitive monomer, and a photoinitiator, and wherein the polymer of the ultraviolet (UV) transparent oil includes a polyurethane oligomer. 
 
     
     
       10. The composite of  claim 9 , wherein the polymer comprises a UV oligomer, the UV oligomer includes the polyurethane oligomer, the UV transparent oil contains 20%-80% (by weight) UV oligomer, 18%-70% (by weight) photosensitive monomer, and 1%-10% photoinitiator. 
     
     
       11. The composite of  claim 9 , wherein the polymer further comprises modified acrylate oligomer.
